Abstract
(Allyloxy)methyl-Crown Ethers have been used as metal cation carriers in a bulk liquid membrane system. Competitive transports by the AMDT18C6 and the AM18C6 are selective for Pd(��) ion and Pb(��) ion over other transition metal cations respectively. Studies of complexations of (Allyloxy)methyl-Crown Ethers with metal cations have been carried out by titration calorimetry and potentiometry.
